Synopsis:

The obsidian-black Peterbilt 359 should have been everything Garth Heller wanted. Instead, his dream rig carries something that has been waiting far longer than he could imagine.
Deep within its engine block lies a malevolent force, a remnant of an ancient cosmic evil forged from the Spear of Destiny itself. Once Garth takes possession of the truck, something begins taking possession of him. His pride gives way to blackouts, madness, and violence as the darkness within the rig steadily consumes his mind and twists his soul into a vessel for horror.
Soon, Garth is left with missing memories, unbearable guilt, and unspeakable crimes he cannot escape. And the evil isn’t finished. When the Peterbilt passes to Harry Smith, a broken man with his own despair, the nightmare finds a new owner and the cycle begins again.
Dark with occult mythology, cosmic terror, and psychological horror, The Obsidian Rig transforms a symbol of freedom into something monstrous, carrying an ancient evil down an endless road in search of its next victim.
Author Bio:

Earl D. Coobs grew up in the rolling hills of Northeast Iowa, where small-town values and the quiet beauty of the countryside shaped the way he sees people, places, and the stories hidden beneath everyday life.
For more than fifty years, Earl made his living as a professional truck driver, logging millions of miles across America’s highways and back roads. Those decades behind the wheel gave him a front-row seat to the country’s grit, kindness, loneliness, humor, and hard truthsโexperiences he carried with him for years before putting them to paper.
Now retired and living in Reidsville, Georgia, Earl spends his days enjoying nature, family, and the slower rhythm of a life well earned while finally sharing the stories that stayed with him throughout his years on the road.
His books include The Gospel of Silas, Bus Number 43, and The Obsidian Rig, with more stories still to come.Website: https://coobsauthor.com/
